Once this is worked on more the pages can be moved around. Currently, I've only been working with the google calendear api.
I wanted to see if I could change the timezone for an imported calendar.

I've been looking at this documentation: http://code.google.com/apis/calendar/data/1.0/developers_guide_protocol.html#AuthClientLogin

First you need to get authentication. This done with curl by doing:
curl -v -d "accountType=HOSTED_OR_GOOGLE" -d "Email=email" -d "Passwd=password" -d "service=cl" -d "source=concordconsortium-fixtmz-1" https://www.google.com/accounts/ClientLogin
Note: that is an lowercase L not a one in the service name

Then you request a list of calendars with this authenication:
curl -H "Authorization: GoogleLogin auth=put auth token from response above here" -H "Content-Type: application/atom+xml" http://www.google.com/calendar/feeds/default/allcalendars/full | xmllint --format -

This returns a redirect so update the request above to follow it
